IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 189,040, dated April 3, 1877; application filed October 11, 1876.

a curved recess and catch combined in one casting, in such manner as to co-operate with the handled cam, to lock the sash automatically when closed, as hereinafter more fully described and definitely claimed. This device will also co-operate in the same manner with the class of sash-holders formed of a circular disk pivoted eccentrically to the sash, and provided with a handle for revolving the same.

In the drawing, Figure 1 is a side elevation of a portion of a sash with my improved device attached. Fig.2 is a face view of the cam; Fig. 3, a cross-section of the cam and screw; Fig. 4, a face view of the plate, curved recess, and catch; Fig. 5, a side view of the same.

In the drawing, A represents a cam, provided with a gravity-handle, E, shoulder-stop a, and enlarged part a, similar to that shown in Patent No. 177,247, the enlarged opening replaced by a smaller hole, through which vent it defacing the frame F. H shows a nail or screw, the head making a stop for the bandle E, to prevent the defacement of the frame F by the shoulder-stop a on the downward motion of the sash D. I represents a fastening-plate, having in the middle a curved recess, K, and on. the side a catch, L, combined in one casting, and let into and secured to the frame F by screws m m.

To close the sash, the handle E is turned against the stop *H, and held thus until the descent has been accomplished. On letting go of it the handle E falls, by gravity, under the catch L, the curved recess K allowing the cam A to turn for that purpose, and the sash is automatically locked in position.

What I claim as my invention is- The combination of the fastening-plate-I, having a curved recess, K, and catch L, with the cam or eccentric A, having handle E, or its equivalent, substantially as shown and described, for the purpose set forth.
